Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/html2wml-0.4.11+dfsg/wml_compilation/kannel/wmlc.c FINAL RESULTS: data/html2wml-0.4.11+dfsg/wml_compilation/kannel/wmlc.c:70:12: [2] (misc) fopen: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). out_fd = fopen(output, "w"); data/html2wml-0.4.11+dfsg/wml_compilation/kannel/wmlc.c:48:16: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). size_t len = strlen(input); data/html2wml-0.4.11+dfsg/wml_compilation/kannel/wmlc.c:51:3: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(output, input, len); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 83 in approximately 0.06 seconds (1491 lines/second) Physical Source Lines of Code (SLOC) = 56 Hits@level = [0] 0 [1] 2 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 53.5714 [1+] 53.5714 [2+] 17.8571 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
